To evaluate the effect of an employer-mandated obstructive sleep apnea (OSA) program on the risk of serious preventable truck crashes.
Data are from the first large-scale, employer-mandated program to screen, diagnose, and monitor OSA treatment adherence in the US trucking industry. A retrospective analysis of cohorts was constructed: polysomnogram-diagnosed drivers (OSA positive n = 1,613, OSA negative n = 403) were matched to control drivers unlikely to have OSA (n = 2,016) on two factors affecting crash risk, experience-at-hire and length of job tenure; tenure was matched on the date of each diagnosed driver's polysomnogram. Auto-adjusting positive airway pressure (APAP) treatment was provided to all cases (i.e. OSA positive drivers); treatment adherence was objectively monitored. Cases were grouped by treatment adherence: "Full Adherence" (n = 682), "Partial Adherence" (n = 571), or "No Adherence" (n = 360). Preventable Department-of-Transportation-reportable crashes/100,000 miles were compared across study subgroups. Robustness was assessed.
After the matching date, "No Adherence" cases had a preventable Department of Transportation-reportable crash rate that was fivefold greater (incidence rate ratio = 4.97, 95% confidence interval: 2.09, 10.63) than that of matched controls (0.070 versus 0.014 per 100,000 miles). The crash rate of "Full Adherence" cases was statistically similar to controls (incidence rate ratio = 1.02, 95% confidence interval: 0.48, 2.04; 0.014 per 100,000 miles).
Nontreatment-adherent OSA-positive drivers had a fivefold greater risk of serious preventable crashes, but were discharged or quit rapidly, being retained only one-third as long as other subjects. Thus, the mandated program removed risky nontreatment-adherent drivers and retained adherent drivers at the study firm. Current regulations allow nonadherent OSA cases to drive at another firm by keeping their diagnosis private.

评估雇主强制实施的阻塞性睡眠呼吸暂停(OSA)项目对严重可预防卡车碰撞风险的影响。
数据来自美国卡车运输行业首个大规模的雇主强制项目,该项目用于筛查、诊断和监测OSA治疗依从性。构建了队列的回顾性分析:将多导睡眠图诊断的司机(OSA阳性n = 1613,OSA阴性n = 403)与不太可能患有OSA的对照司机(n = 2016)在影响碰撞风险的两个因素上进行匹配,即入职时的经验和工作任期长度;任期根据每个诊断司机的多导睡眠图日期进行匹配。为所有病例(即OSA阳性司机)提供自动调压气道正压(APAP)治疗;客观监测治疗依从性。病例按治疗依从性分组:“完全依从”(n = 682)、“部分依从”(n = 571)或“不依从”(n = 360)。比较各研究亚组每100,000英里可预防的运输部报告的碰撞事故。评估稳健性。
在匹配日期之后,“不依从”病例的可预防运输部报告的碰撞率比匹配对照组高五倍(发病率比 = 4.97,95%置信区间:2.09,10.63)(每100,000英里分别为0.070和0.014)。“完全依从”病例的碰撞率与对照组在统计学上相似(发病率比 = 1.02,95%置信区间:0.48,2.04;每100,000英里为0.014)。
未坚持治疗的OSA阳性司机发生严重可预防碰撞的风险高五倍,但很快被解雇或辞职,其保留时间仅为其他受试者的三分之一。因此,强制实施的项目清除了有风险的未坚持治疗的司机,并在研究公司保留了坚持治疗的司机。现行法规允许未坚持治疗的OSA病例通过隐瞒诊断在另一家公司驾驶。
